Root canals

We offer our patients the latest in state-of-the-art root canal therapy! A root canal is required when the soft tissue inside of a tooth becomes infected and inflamed. Because the soft tissue, or pulp, of the tooth contains nerves and blood vessels, when the damage goes beyond what can be treated with a traditional filling, we have to perform a root canal to preserve the tooth. The need for a root canal can be caused by a deep cavity, a cavity that is not treated, an injured tooth or repeated dental procedures that upset the soft tissue of the tooth. 

Receiving a Root Canal

  • The tooth will be numbed with a local anesthetic.
  • A rubber dental dam will be placed to keep the treatment area sterile.
  • A small hole will be drilled in the tooth for access.
  • Using special dental instruments, the root canals and pulp chamber will be cleared of infection.
  • Once all infected pulp tissue is removed, the canals will be properly disinfected.
  • The canals are then prepped to receive a strengthening filler.
  • Root canal filling is used to fill the space and seal the canals.
  • A filling will also be placed into the access hole that was drilled.

The root canals of a tooth have a primary root and many, smaller, secondary branches; the whole root system needs to be sealed during a root canal for the procedure to prove successful long term.

This procedure can be completed in one visit, but more extensive cases may require another appointment. For a couple days following the completion of the root canal, the tooth may feel a tad sensitive, especially if there was already existing pain from the inflammation prior to the procedure. This mild discomfort can be controlled with over-the-counter pain medication. Patients typically return to their normal activities the following day.

Root canals are common procedures. You should not experience any problems after your root canal, but if you do, please contact our office immediately.
